A cranial mediastinal mass was observed radiographically in two 5-year-old adult male ferrets (Mustela putorius furo), both with histories of chronic episodic vomiting, dyspnea, and lethargy. Malignant lymphoma, a common neoplasm observed in ferrets, was considered the most likely diagnosis. Cardiomegaly and splenomegaly were also present. Histologically both mediastinal masses were composed of thymic epithelial cells and small lymphocytes, establishing a diagnosis of thymoma. Thymoma should now be included in the differential diagnosis of a cranial mediastinal mass in ferrets.

A 2-phase study was conducted to evaluate the ability of the NEB-1 strain of porcine reproductive and respiratory syndrome virus (PRRSV) to potentiate common bacterial pathogens of swine. In phase I, 25 of 50 4-5-week-old specific-pathogen-free (SPF) pigs were exposed to NEB-1 PRRSV (day 0). Seven days after virus inoculation, 8 groups received 1 of 4 bacterial pathogens: Haemophilus parasuis, Streptococcus suis, Salmonella cholerasuis, and Pasteurella multocida. The ability of NEB-1 PRRSV to produce clinical disease, viremia, neutralizing antibody, gross and microscopic lesions and to potentiate bacterial pathogens was assessed. Response to NEB-1 PRRSV was similar among inoculated pigs; prolonged hyperthermia, lethargy, mild to moderate dyspnea, and cutaneous erythema were consistent clinical signs. No clinical differences were observed in groups after bacterial challenge. Virus was isolated from serum at weekly intervals through the end of the study, and all PRRSV-inoculated pigs had seroconverted by study termination. Two of 5 pigs died in non-PRRSV-inoculated groups challenged with H. parasuis and Streptococcus suis. Mortality in PRRSV-infected pigs was limited to 1 of 5 pigs from the Salmonella cholerasuis-challenged group. Gross lesions were seen in pigs dying after inoculation in H. parasuis- and Streptococcus suis-inoculated groups, in Salmonella cholerasuis- and P. multocida-challenged pigs, and in 1 non-PRRSV-inoculated control pig. Microscopic lesions consisted of mild to moderate proliferative interstitial pneumonia, nonsuppurative myocarditis, lymphoid hyperplasia, and nonsuppurative encephalitis in PRRSV-inoculated pigs. Findings in phase I indicated that NEB-1 PRRSV does not potentiate bacterial disease while inducing consistent clinical signs, viremia, seroconversion, and microscopic lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-one patients (mean age 68 +/- 8 years) with dual-sensor (QT+activity) DDDR pacemaker were randomly assigned to a crossover, double-blind study in order to evaluate their quality-of-life scores. All pacemakers were implanted for sick sinus syndrome (8 patients) or complete heart block (13 patients). The pacemakers were randomly programmed to VVIR or DDD pacing modes for 2-week periods and then the pacing mode was switched for another 2-week period. At the end of each period, the quality-of-life was evaluated by a questionnaire with regard to cardiovascular symptoms, physical activity, psychosocial and emotional functioning, and self-perceived health. Nineteen questions were scored 0-5 points each. Significant improvement in the mean total quality-of-life score (20.5 +/- 14.9 vs 34.8 +/- 17.4) as well as in dyspnea on effort, dizzy spells, palpitation, sweating, fatigue, lethargy, emotional functioning, and self-perceived health was observed during DDD compared to VVIR pacing. No question was scored in favor of VVIR pacing mode. Significant improvements during DDD pacing was demonstrated in all subgroups of patients (sick sinus syndrome, chronotropically competent and incompetent patients, and patients with high degree AV block). Eighteen patients preferred DDD pacing mode, while only one preferred VVIR pacing mode. Two remaining patients expressed no preference. The results suggest that DDD pacing offers better quality-of-life than dual sensor VVIR pacing in all subgroups of patients commonly indicated for pacemaker implantation.

The Southwest Oncology Group (SWOG) studied the response rate and toxicity of merbarone (1,000 mg/m2 IV continuous infusion days 1-5, q 21 days) in patients with advanced metastatic renal cell carcinoma. Among 36 eligible patients, there was one partial response for a response rate of 3% (95% C.I. 0.1-15%). There were no mixed responses. There were no treatment related deaths or adverse drug reactions. Significant anemia, diarrhea, and hypercalcemia were observed. Mild to moderate degrees of malaise/fatigue/lethargy, dizziness/vertigo, hyperglycemia, creatinine increase, nausea, vomiting, weight loss, pedal edema, dyspnea, and granulocytopenia were noted. Merbarone does not have significant activity as a single agent in advanced renal cell carcinoma.

Simian T-cell leukemia virus type 1 (STLV-1), a type C retrovirus associated with leukemia/lymphoma in Old World monkeys, is closely related to human T-cell leukemia virus type 1, the etiologic agent of adult T-cell leukemia/lymphoma in humans. In a colony of 3200 baboons, the prevalence of antibodies to STLV-1 is more than 40%. Seropositivity is more frequent in female baboons than in males and increases with age. Of 27 STLV-1 antibody-positive baboons with non-Hodgkin's lymphoma, 20 were females and 7 were males, ranging in age from 3 to 21 years (mean, 13 years). Non-Hodgkin's lymphoma was not found in STLV-1 antibody-negative baboons. Clinical signs and laboratory findings were variable but generally included lethargy, low body weights, anemia, dyspnea, lymphadenopathy, hepatosplenomegaly, pneumonia, nodular skin lesions, and leukemia with or without multilobulated lymphocytes in peripheral blood. Radiography revealed pulmonary infiltrates consistent with pneumonia in 17 of the baboons. Serum chemical values were normal except for hypercalcemia in one baboon. Lymphocytosis was found in 18 of the baboons, with leukemia diagnosed in 11. At necropsy, variable enlargement of lymph nodes and other lymphopoietic tissue was usually found. Pale tan to white space-occupying foci typical of proliferative lymphoid tissue were often found in various organs, including lungs, spleens, livers, skin, and hearts. The lungs in 14 baboons had thickened pleuras, congestion,edema, and large tan to brown areas of consolidation.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors' primary purpose was to identify home healthcare needs of adults (N = 244) living with HIV disease/AIDS. The study followed a retrospective chart review of a stratified random sample of cases discharged during 1991 from a certified home health agency (CHHA) in New York City. Frequently observed signs and symptoms included dyspnea, weakness, fatigue/lethargy, pain, ataxia, cough, skin lesions, and memory deficit. Additional problems identified included inadequate nutrition, issues related to compliance with prescribed medications, inadequate in-home support systems, inadequate facilities/utilities in the home, financial concerns and lifestyles that included drug/alcohol abuse and tobacco use. The results suggest that the health care needs of people living with HIV disease/AIDS in the home care setting are multifaceted and extend beyond the clinical manifestations of HIV disease.

A 34 year old sawmill maintenance engineer developed a dry cough that was associated with widespread wheezes and crackles in his lungs. His symptoms worsened, with work related lethargy, fever, and breathlessness, and the loss of a stone in weight. At that time, while still at work, he had a neutrophil leucocytosis and increased concentration of gamma globulins. When seen subsequently some two months after stopping work, his chest radiograph and lung function tests were normal, but the cells recovered at bronchoalveolar lavage showed an increase in lymphocytes and mast cells, a pattern consistent with extrinsic allergic alveolitis. Serum precipitins were identified to extracts of sawdust, wood chips, and bark from the sawmill, and to eight species of mould grown from these samples. Specific IgG binding inhibition studies suggested that a common epitope present on Trichoderma koningii might be responsible for the cross reactivity of the patient's serum with the wood and fungal extracts. A diagnosis of wood associated extrinsic allergic alveolitis was made and since changing his job the patient has remained well. Wood associated allergic alveolitis has not previously been described in British sawmill workers, but has been reported in Sweden, with a prevalence of 5%-10% in exposed workers. A review of published data suggests extrinsic allergic alveolitis in wood workers is primarily caused by inhalation of the spores of contaminating fungi, but inhaled wood dust may exert a synergistic effect.

We studied the relation between the amount of textile and other soft fiber wall materials used in the office and the symptoms related to sick building syndrome in two identical, mechanically ventilated, eight-story office buildings. The study population consisted of 400 workers (85% of the source population): 264 males (66%) and 136 females (34%). A self-administered questionnaire inquired about the occurrence of symptoms and related personal and environmental determinants. The office environment was assessed concurrently. Exposure was defined as the surface area of textile or other soft wall material (SWM) in the office. The outcomes were formed using the 7-d prevalences of individual symptoms, including mucosal irritation score (eye irritation, nasal dryness, nasal congestion, pharyngeal irritation); allergic reaction score (eye irritation, nasal congestion, nasal excretion, sneezing); asthma reaction score (wheezing, breathlessness, cough); skin reaction score (dryness, itch, or irritation, rash); and general symptom score (headache, lethargy). In the logistic regression controlling for potential confounders, the adjusted odds ratio for the symptoms of mucosal irritation was 1.82 (95% confidence interval [95% CI] = 1.14, 2.90) in the low-exposure group, compared with the unexposed reference group; and 2.46 (95% CI = 1.15, 5.28) in the high-exposure group, compared with the reference group. Corresponding odds ratios for the symptoms of allergic reaction were 1.82 (95% CI = 1.14, 2.90) and 3.16 (95% CI = 1.41, 7.09). No difference was found in the risk for asthmatic or skin reactions or general symptoms. The results support a hypothesis that textile and other soft-fiber wall materials used in the office environment are possible determinants of sick building syndrome.

The results of clinical and radiographic examinations of 15 dogs with confirmed malignant histiocytosis (MH) were reviewed. The most common clinical signs were anorexia (14 dogs), weight loss (13 dogs), lethargy (13 dogs), anaemia (11 dogs), and dyspnoea and/or coughing (8 dogs). Radiographs revealed abnormalities in all dogs, either intrathoracic (pulmonary nodules or consolidation [7 dogs], mediastinal masses [10 dogs], and incidentally pleural effusion [3 dogs]) or abdominal (hepatomegaly [6 dogs] and splenomegaly [2 dogs]), or both. MH occurs relatively frequently in Bernese Mountain dogs. Both clinical and radiographic signs are non-specific, but when they are present in a middle-aged Bernese Mountain dog, MH should be included in the differential diagnosis.

The Lelystad virus or one of two US isolates (VR2385, VR2431) of porcine reproductive and respiratory syndrome virus were given intranasally to 25 4-week-old cesarian-derived colostrum-deprived pigs. Pigs from these groups were necropsied at 1, 2, 3, 5, 7, 10, 15, 21, or 28 days postinoculation. The Lelystad virus and VR2431 induced mild transient pyrexia, dyspnea, and tachypnea. VR2385 induced labored and rapid abdominal respiration, pyrexia, lethargy, anorexia, and patchy dermal cyanosis. All three isolates induced multifocal tan-mottled consolidation involving 6.8% (n = 9; SEM = 3.4) of the lung for Lelystad, 9.7% (n = 9, SEM = 2.7) of the lung for VR2431, and 54.2% (n = 9, SEM = 4.4) of the lung for VR2385 at 10 days postinoculation. Characteristic microscopic lung lesions consisted of type 2 pneumocyte hypertrophy and hyperplasia, necrotic debris and increased mixed inflammatory cells in alveolar spaces, and alveolar septal infiltration with mononuclear cells. Lymphadenopathy with follicular hypertrophy, hyperplasia, and necrosis was consistently seen. Similar follicular lesions were also seen in Peyer's patches and tonsils. Lymphohistiocytic myocarditis and encephalitis were reproduced with all three isolates. Clinical respiratory disease and gross and microscopic lung lesion scores were considerably and significantly more severe in the VR2385-inoculated pigs. All three viruses were readily isolated from sera, lungs, and tonsils throughout the 28 days of the study. The lymphoid and respiratory systems have the most remarkable lesions and appear to be the major site of replication of these viruses. This work demonstrated a marked difference in pathogenicity of porcine reproductive and respiratory syndrome isolates.
